Credit Card with CVV2

[michael_s]

I discovered that the cc.php file in the package by googlejunky did not work at all. I've fixed the file so it works now and updated the package with a popup explanation window for those customers who do not know what a credit card security code is or where to find it. I've also updated the instructions with the additional information needed to get this contribution to work with osCommerce RC1 or later.

Please note that any store that uses this contribution also NEEDS to use one of the credit card number encryption contributions and modify it to encrypt the CVV2 as well. As a further precaution I would also install one of the contributions that erases the credit card number when it is no longer needed and modify that to erase the CVV2 as well. Erasing the CVV2 when it is no longer needed is probably also necessary to comply with banking regulations that prohibit a merchant from retaining the credit card security code any longer than is needed to process the order.
